HAND-STAMP.

Specification of Letters Patent No. 15,574, dated August 19, I856.

Be it known that I, EDWIN A. RUSSELL, of v Hookset, in the county ofMerrimack and State of New Hampshire, have invented a new and useful orImproved Automatic Hand-Stamp; and I do hereby declare that the same isfully described and represented in the following specification and theaccompanying drawings, of which Figure 1, is a top view of said machine;Fig. 2, a side elevation of it; Fig. .3, a front view of the camgrooves, and vibrator by which the spring trip hammer, .(to behereinafter described) is operated; Fig. 4:, a vertical, central andlongitudinal sectionof the machine.

In these drawings, A, exhibits a platform supporting an inking bed ortable B, and another similar bed or table 0, whose office is to sustaina sheet of paper or other article to be imprinted or stamped. Arrangedwith respect to said bed and upon the platform A, as seen in thedrawings, is a vertical column or post D, upon the upper end of which isplaced an arm or hand lever, E, which turns horizontally on said post asa fulcrum and carries at or near its middle, a stamp, E, whose verticalrod, a, slides up and down freely in the arm or lever and is supportedon a spring G, arranged within the lever as shown in Figs. 2 and 4; suchspring serving to elevate the stamp immediately after it has been forceddownward by a blow from the spring trip hammer to be hereafterdescribed. This hammer is shown at I. It is formed in the shape of alever, and turns vertically on a fulcrum 7), arranged in the lever E,and directly over the fulcrum thereof, the said hammer having a smartspring K, applied to it and the lever E, in the position as shown in thedrawings. The rear arm of the hammer extends into a curved cam plate L,which is fixed and supported upon the top of a post M, erected on theplatform A, in the position as shown in the drawings. This cam plate isconstructed with grooved recesses 0, cl, 6, f, and g, arranged withrespect to one another and formed as shown in Fig. 3, and it also has atongue or vibrator, h, which is placed at the junction of the twogrooves c, and d, or is hinged to the vertex of the angle of their uppersides and so that it may play across and close each of the grooves 0,cl, and guide the rear arm of the trip hammer across said groove orprevent it from entering the same during or immediately 'after itspassage out of the other groove.

In operating with the machine, the longer arm of the lever, E, is tobeseized by the hand of an attendant and the lever moved so as to carrythe stamp directly over the inking bed B. While this is being done, therear arm or tail of thetrip-hammer I, will be madeto travel downthegrooved, against the vibrator h, and into the space, 6, and toward andinto the vertical groove f, of the cam plate L, the trip hammer beingraised thereby above the stamp rod. As soon as the rear arm of the triphammer enters the vertical groove f, the trip hammer will be forceddownward by the action of its spring K, and striking upon the top of theslider of the stamp will depress said stamp quickly upon the inking bed,the force of the blow being sufficient to move the stamp rod a shortdistance beyond the hammer after the latter has struck a stop on, suchmovement being such as to cause the stamp to descend upon the inkingbed. Subsequently or immediately afterward it will be raised a shortdistance ofi the same by the action of the spring G. This operation willcause the lower surface of the stamp to be inked. Next, the stamp leverE, istobe moved laterally toward and over the bed C, on which it may besupposed there has been previ ously laid a piece of paper, to be stampedor printed. During such movement of the said lever, the tail or rear armof the trip hammer. will pass down the groove 0, and against thevibrator D, and will move the latter across the groove (Z, and move into ward and enter the recess 6, and thence pass into the vertical grooveg. At the instant, the tail of the hammer enters the groove Gr, thespring of the hammer will depress the trip hammer smartly upon theslider of the stamp causing the stamp to be operated or moved withrespect to the bed C, substantially as hereinbefore described withreference to the inking bed B, the stamp being made to give animpression on the paper on the bed C. Thus by alternately moving thestamp from one bed to the other it will be inked and caused to give animpression.

I do not claim the combination of a movable stamp carrier or lever withan inking bed and a bed for supporting a piece of paper or any articleto be printed, the stamp being moved by one hand of a person alternatelyfrom one bed to. the other and driven downward by a blow from the otherhand of such person or a hammer held therein, as I am aware that such ahand press or stamp is not new, but

What I do claim is- Combining with the movable lever or stamp carrier Eand beds B, and C, a mechanism substantially as described whereby,during and by the lateral movements of the said lever or stamp carrierfrom one bed to the other, the stamp shall not only be struck or forceddownward but raised off the same in manner and for the purpose asspecified,

such mechanism being a trip hammer with its operating spring, a cam L,and a spring 15 G, constructed and made to act with respect to the stampand its carrier essentially as stated.

In testimony whereof I have hereunto set my signature this 16th day ofJune A. D. 20 1856.

EDWIN A. RUSSELL.
